Abstract
processo para fabricar óxido de cálcio ou cimento portland comum a partir de rochas e minerais contendo cálcio. os aspectos da invenção incluem um método para produzir um material de cimento compreendendo a etapa de: primeiro, reagir um material de partida contendo cálcio com um primeiro ácido para produzir um primeiro sal de cálcio aquoso; segundo, reagir o primeiro sal de cálcio aquoso com um segundo ácido para produzir um segundo sal de cálcio sólido; em que o segundo ácido é diferente do primeiro ácido e o segundo sal de cálcio é diferente do primeiro sal de cálcio; e tratar termicamente o segundo sal de cálcio para produzir um primeiro material de cimento. preferivelmente, mas não necessariamente, durante a segunda etapa de reação, a reação entre o primeiro sal de cálcio e o segundo ácido regenera o primeiro ácido.
